Ambler, Penn. - MEN Micro Inc. now offers the P506 Quad CAN Bus Interface PCI mezzanine card (PMC), operating at 32-bit/33-MHz, that provides four independent, galvanically-isolated controller area network (CAN) interface channels on a single card.

Each interface provides a programmable loop-back mode for self-test operation as well as signaling and interrupt capabilities for receiver and transmitter error states.

The P506's interfaces are executed via IP cores within an onboard FPGA (field-programmable gate array).'Corresponding line drivers are implemented on a specialized USM (Universal Submodule) module that plugs directly onto the PMC board. MEN Micro's USM concept enables easy, cost-effective updates to a board's functionality through the implementation of different IP cores with minimal development time.

The interfaces support CAN protocol 2.0A/B with standard or extended data frames from 0 to 8 bytes and a programmable data rate of up to 1 Mbit/second per ISO 11898-1/2.'

The P506 provides support for remote frames under CAN Layer 2 as well as CANopen master and slave, and is suitable for any PMC-compliant host carrier board in any type of bus system (i.e. cPCI, VME or any standalone SBC).

The new PMC is designed for use in mobile and safety critical harsh environments as found in industrial control, telecommunications, medical engineering, avionics and other transportation applications.

It is qualified to perform in an extended temperature range of -40°C to +85°C at a maximum of 95% RH (non-condensing). Conformal coating is available on request for added protection against dust and humidity.

The unit is rated to withstand shock at 15 g/11 ms, bumps up to 10 g/16 ms and sinusoidal vibration of 1 g/10 Hz to 150 Hz.'EMC protection conforms to EN 55022 for radio disturbance, IEC1000-4-2 for electrostatic discharge (ESD) and IEC1000-4-4 for electrical fast transient/burst testing.
